Product Information

Supports Protein Metabolism

Citrulline is a non-essential amino acid that is an important intermediate in the urea cycle, functioning along with Arginine and Ornithine to rid the body of ammonia, a byproduct of protein metabolism. Because Citrulline is a precursor of Arginine, it provides a readily available source material for Arginine production, which in turn, can be used for the production of Nitric Oxide (NO). NO plays a fundamental role in vascular function and blood flow. Citrulline therefore, not only supports detoxification pathways, but also supports NO production and a healthy cardiovascular system.

Now Citrulline Highlights:

  • Cardiovascular Health
  • Pharmaceutical Grade (USP)
  • Promotes Nitric Oxide Production
  • Supports Vascular Blood Flow

No complaints - I think the quantity may be below the recommended amount for a pre workout, but I notice a clear distinct improvement in recovery on dates used vs. dates not used.*

Can't really tell if it's helping with working out or not. Nice to only have to take 1 or 2 pills a day though*

I stack this product with my pre-workout along with some L-Arginine to assist with my pump so far I haven't noticed a difference but I guess it's a matter of time*
